Indices of records in A245203 (= least k>=0 such that 4n+3 is the mean of primes 4(n-k)+3 and 4(n+k)+3). A245205

For positive n with prime decomposition n = ∏_j=1..m (p_j^k_j) define A_n = ∑_j=1..m (p_j*k_j) and B_n = ∑_j=1..m (p_j^k_j). This sequence gives those n for which A_n and B_n are both prime and B_n = A_n + 2 (i.e., form a twin prime pair). A185718
